For the 0.31 release it was a separate package: https://www.npmjs.com/package/@jupyterlab/vega3-extension
That package is still available on npm, so you should be able to install it on 0.31 with: jupyter labextension install @jupyterlab/vega3-extension In JupyterLab master and moving forward it is built into JupyterLab itself, so no additional extension is needed (but vega2 will be a separate package moving forward). What version of lab are you using? How did you try to install/use it?
